Plural of imposter; people who pretend to be someone else or claim to have skills or qualities they don't actually have.
From Latin imponere (in- meaning in, ponere meaning to place), literally 'to place upon' or impose; gradually came to mean someone who tricks others by posing as someone else.
Interestingly, 'impostor syndrome'—where accomplished people doubt their abilities and feel like frauds—might exist because we're all somewhat aware that we're all performing versions of ourselves in different contexts, making the line between 'imposter' and 'authentic self' fuzzier than we'd like to admit.
